This is what I remember:
I think the author was not a professional writer but the story was cited in other webs.
A main theme was "uploading".
The pace remembered me to "Accelerando" by Charles Stross: it covers a time period between the near future and the far future.
The main character have fallen to a "town" that is surrender by walls where there is a landscape painted. It is a kind of "natural reserve" for humans. I think this is the first part of the story.
The civilization out of the "natural reserve" was not very human friendly and the humans in there didn't know about outside.
The main character was the first uploaded person. The story explains how he makes profit from this initially and how the different copies of him interact.
I think that, at some point, there are two characters called Alpha and Omega.
